mojhsa [17]

Answer:

b) 5 (x-3)\\c) 4 x + 3 y-15- 3 y + x\\e) -20 - 3 x + 5 + 8 x

Step-by-step explanation:

We are given the following expression in the question:

5x-15

a)

5 (x + 15)\\=5(x) + 5(15)\\=5x + 75

which is not equivalent to the given expression.

b)

5 (x-3)\\=5(x)-3(5)\\=5x-15

which is equivalent to the given expression

c)

4 x + 3 y-15- 3 y + x\\=4x+x+3y-3y-15\\=5x-15\\=5(x-3)

which is equivalent to the given expression.

d)

-7 y-6 x- 8 y + x\\=-7y-8y-6x+x\\=-15y-5x\\=-5(x+3y)

which is not equivalent to the given expression.

e)

-20 - 3 x + 5 + 8 x\\=-3x+8x-20+5\\=5x-15

which is equivalent to the given expression.
